Water Absorption of Sulfur Dioxide in a Packed Tower
Abstract: The absorption of the design aims to remove harmful substances in the exhaust of industrial venting. The sulfur dioxide absorption water, design and operating conditions for the task is: At the temperature of 20 and under the atmospheric pressure，the gas mixture (air + SO2)in the amount of procesing : 10000m3/h, volume fraction of sulfue dioxide in the inlet gas mixture:5﹪, emissions (sulfur dioxide by volume) : 0.02﹪. Design scheme: The sulfur dioxide absorption water, to belong to medium solubility absorption process, in order to improve the mass transfer efficiency, choose counter-current absorption process, because water absorbent do, and sulfur dioxide, not as products, so the pure solvents. Choice of filler: the process of water absorption of SO2, the operating temperature and operating pressure is low, the industry usually use plastic bulk packing. In the plastic bulk packing, plastic ladder ring packing performance is better, therefore the DN38 polypropylene ladder ring packing is being choiced.The design of the tower diameter is 2.4m, tower height is 15m,skirt height is 4.8m,packing layer height is 6m.Effective thickness of the cylinder, head and skirt is 8mm .
